Question

Solve the equation. 9d + 2d + 3d – 4 = 5d

Answer 1

you add 9d+2d+3d which equals to 14d, then you would subtract 14d to each side. After you subtract 14d to each side, it should look like -4=-9d. So your answer should be 4/9=d

Answer 2

Solution of the equation is d =
`(4)/(9)`

Explanation:

The given expression is 9d + 2d + 3d - 4 = 5d

Now we will add the like terms on the left hand side of the equation.

(9d + 2d + 3d) - 4 = 5d

14d - 4 = 5d

Now we subtract 5d on both sides of the equation.

14d - 5d - 4 = 5d - 5d

9d - 4 = 0

Now we add 4 on both the sides of the equation

9d - 4 + 4 = 0 + 4

9d = 4

Now we divide both the sides of the equation by 9.

`(9d)/(9)=(4)/(9)`

d =
`(4)/(9)`
